lMPROVEMENT IN COOKiNG-STOVES.

The Schedule referred to In these Letters Patent and making part of the name.

I, WILLIAM D. O. LLOYD, of the city of Louisville, county of J efierson and State of Kentucky, have invented a certain new and useful Improvement in Cooking-Stoves, of which the following is a specification.

The nature of my invention consists more especially in providing an air-chamber in the sunk part of the stove-hearth immediately under the fire.

This chamber is formed by a corrugated plate, with ribs on top to hold up the wood.

This plate is neatly fitted in the recess or sunk part of the hearth, and secured in such a manner as to be "almost air-tight, leaving about two or more inches in by means of a small pipe connecting the chamber with an opening in the bottom of the hearth below, thereby preventing all ashes or dirt from entering the air-chamber.

The great advantages which I claim for my improvement are, that, by the use of the air-chamber immediately under the fire, it keeps the plates cool and prevents them from burning, and also prevents theovenplate below from being highly heated, so as to burn the article cooking, and in order further to protect it the plate may be coated with a composition of alum and asbestns, by which, and with the addition of the, heated air constantly rushing in through the chamber, the temperature of the oven becomes perfectly uniform throughout, and may be regulated to any degree of heat required, while all smoke or gas passes ofi' through the holes connecting theoven with the fines of the stove, thereby avoiding all obnoxious vapors in the room where it is used, the openings admitting air into the chamber being closed when necessary by means of sliding covers in order to regulate the temperature in the oven, so that one side of the article cooking may not burn before the other is done air-holes J J J in recess K, and vent-holes Having thus fully described the nature of my invention, a more complete understanding of which may be had by reference to the drawing Figure 1 is a view of the stove with a part of the side left out in order to show the interior of the oven and the situation of the air-chamber in the hearth.

Figure 2 is a view of the front of the stove, showing the hearth with the air-chamber in the recess, and also the covers by which the, holes are closed, and connected with openings in the bottom and sides of the hearth, through which the air is supplied.-

Having thus fully described the drawing,
